5 Important Things to Consider When You Compare Home Water Purifiers

When you compare home water purifiers, there are five very important things to look for. That is if you really want safe home water that is, also, affordable.

The popularity of home purification has meant that better more effective systems have been designed, but there are pretenders among them that are not actually purifiers, at all. Here's how to spot them.

Lead Reduction

Every company should provide product performance data, which includes certification by an independent laboratory, such as Underwriter's. When you compare home water purifiers, you should only consider the products that provide this data, either on the company website or the outside of the box. The percentage of reduction, as well as the contaminant, should be listed.

For clean and safe home water, one of the things that you want to look at is lead reduction. Lead is a hazardous heavy metal that is naturally occurring in many sources, but that doesn't mean that it is safe. There is no safe level for lead consumption. The best products include an ion exchange step for removal. Products that rely on reverse osmosis only reduce lead to the "federal action level"; not good enough.

Cyst Removal

When you compare home water purifiers, you will see that almost all of them (except the pitchers) remove cysts. Many people think that reverse osmosis is the only reliable method for cyst removal. Sub-micron filtration is just as good and costs a lot less. If you want safe home water that is also affordable, look for sub-micron filtration.

THM Reduction

If you look for THM reduction, you will really reduce your choices. The department store models do not reduce THMs. So, they "really" do not provide safe home water.

There is a "cancer epidemic" in industrialized societies and researchers have been trying to find out why this is true. Turns out, THMs in the water are a big part of the problem. There are thousands of cancer-causing chemicals in publicly treated supplies. Many of them are in the environment and the foods that we eat. Sometimes, they are unavoidable, but, if you only compare home water purifiers that reduce THMs by 99% or better, then you can at least protect yourself from that carcinogen.

Real Costs

What's the real cost of safe home water? If you only consider the cost of purchasing, then you would buy a PUR or Brita filter. PUR does make a model that provides effective THM reduction, but it is not the model that you commonly find in department stores. Most people don't yet know about THMs. They think chlorine is the big problem. For people who do know, better models are available, but the price is higher and they have to be ordered on-line.

But, even if you buy the PUR or Brita model that does reduce THMs, your cost of use will be higher. What I mean is that those brands are only good for about 100 gallons, requiring replacement every month of two at a cost of $20 each. The better brands are good for 500 gallons, five times as long, with a cost of only $40. In other words, the cost per year is higher for the inexpensive brands. So, when you compare home water purifiers, look for one that's good for 500 gallons. It just makes good "cents".
